I'm new here, sorry I can't seem to find where to learn how to upload photos as I'll gladly do so. But if one may ask a question while working to get the photo thing figured out I'd appreciate it and many thanks in advance for the help on this.

I have a 15" tall coffee carafe which I'm very sure is silver pate as I don't find any "standard" sterling hallmarks or proofs. It's only markings are a stamp on the bottom: W. & E. S. Co. # 594.

I suspect that #594 = the manufacture item number / catalog identifier. I'd like to try to find out who the manufacturer is along with the item's approximate age. Any help you can give is greatly appreciated.
